Enjoy The 'Ride' With Seekeeper's New Vessel Attitude Control System

Seakeeper says its new Ride VACS system for boats eliminates up to 70% of underway pitch and roll to improve comfort, control — and your confidence!

It's rare to see truly revolutionary companies produce truly revolutionary products for the marine industry, but few people would argue that Seakeeper's gyroscopic stabilization products are anything but revolutionary. Now, Seakeeper announces a new and also potentially groundbreaking vessel attitude control system (VACS) called Ride, and it has nothing to do with gyros, like Seakeeper's other boat stabilization products.

"Attitude control systems are used in air and space technology to control pitch, roll, and yaw underway. Never before has this technology been used in the marine space ... until now," reads the product promotion. "The introduction of Seakeeper Ride opened the door for a new category in the marine industry — a Vessel Attitude Control System."

Simply put, Seakeeper Ride is trim tabs for the "Top Gun" skipper.

As the blades are deployed, they create lift at the transom, managing the vessel's motion instantaneously.

The Ride uses inertial sensing technology to take 1,000 measurements per second, then adjust rotary blades mounted to the transom of the boat at about 100 times per second to combat pitch, roll, and yaw while underway. Net result? Seakeeper claims there's a 70% reduction in the motions the boat's subjected to while running.

Introducing... Seakeeper Ride!

Because the Seakeeper Ride blade deploys and retracts in milliseconds, adjusting the boat's attitude only when needed, the drag duration is reduced compared to traditional transom-mounted systems. The system begins having trim authority at 10 mph and full stabilization benefits begin around 20 to 25 mph.

At the same time, list is eliminated, trim is optimized, hole shot is improved, and heeling angles are adjusted through turns. Ride will initially be available for boats of 19 to 35 feet, with price ranging from $4,500 to $10,500.
